The forward end of the bar 22 is guided b v a shaft 2T that extends thru a slot 28 in the har and b v a keeper lip 29 which is .stampedfrom the frame plate 8 and bent up along 4the inner face of the bar,` The bar 22 is 'yieldingzly urged to the left (Fig. 1) by a sprinfv 30, which is connected at one end with t e ear 25 on the slide bar 22 and at the otheinend with 'a hook 31 that is stam d outwardly from the plate S, the forwa projection of the bar being limited b v engagement-of the forward end of-the slot- 28 with the shaft '27, such projection being sufficient to 'effect engagement of a, stud 33 on the bar with the free end of a rocking lever, whereby the slide bar is actuated, as presently described;

Pivotall mounted on the bar 22 is a push pawl 34,1 le tooth of which lies on a.l ratchet wheel 35 itbat is fixed on the platen roll 10so that when the bar 22 is moved forwardlyupon o ration of the main man chine, the' slide ar will. advance the platen one space, return movement of thebar under tension of its'spring 30 dragging the pushpa'ivl back to position it for a succeeding o eration;

Rotatably mounted at the forward=end of the frame lates is a take-up roller 38, comprising a )ody member having a. stud 39 at one end rotatable in the frame plate 8, and spaced 'collars at the opposite end adapted for receiving a slotted portion of late 9, whereby the roller ma)r be removab y mounted on the frame plates and held against longitudinal displace` ment. The roller is held against lateral displacement by a. latch 55, similar to the latch 55 4for the primary rewind roller presently described. .The roller 38 may be termed a secondary roller in-that it is adapted for carrying a carbon opy of the record strip,

- the primar;r roller carrying` the original of the strip and being located in a more convenient position on the frame than is the secondary roll. f'

Mounted on` the table L 7 to the rearof the secondary roller 38 is a. U frame 40,

'mounted on the having a bearing aperture 41 one of its arms and a slot '42 inits other arm registerin lwith the bearing aperture and openimr thru the rear edge of the frame arm.

-Iounted4 in the frame 40 is the primary 7n rewind roller 43, having a stud 44 rotatable in the bearing a rture 41 of one of the frame arms and loving spaced collars 45, 45' adjacent its opposite end seated within the slot 42 in the opposite frame arm, the 75 collar 45' constituting a pinionwhereby the rewindr roller is operated, as presently described.

The-'roller 43l has a longitudinal groove 46 and seated` in ysaid ove is a spring 80 fingern, one end of w ich is attached tu the roller while the other end is free, so thatthe record stri ma be located within the groove '44 an hel in place byfthe springnf'er. 85 Rotatably' mounted on the slotted ami-ot the frame-40 isla friction gear wheel 4,8, preferably comprising two toothed'members 49, 50, and a Vspringmvasher 51, -which'latter is held in place by abolt 52 thatextends 90 thru the `Washer, thru hothof the toothed members and thru the frame One of the toothed,members' 48 mesheswith the pinion 44 on-the roller 43 .to-drive-.the same when the friction gear is actuated as; resently set forth. The rewind roller driven by the pinion 38 fromv a gear 53 laten shaft, through. au idler gear.-53" an a. friction 'gear 54`similar to the frictionfgear wheel 48.

This is accomplished thru 110 the aperture ,and slotbearings in the frame platos 8. 9, and in the arms of the U `frame 40, the studs 39 and 44 rotating in the a A r.- tures, and the op osite ends of the ro ers in the Aslots. TE locate the rollers in their mountings the studs are projected into theY apertures -and the opposite ends of the rollers sented.: .in theslots. 'a When so positioned, therollersro" lhs' chored byV latches 55 which'are' pvtally'w! mounted on a ame plste'or frame am respectively an have hooked; ends 55 adapted to drop over the roller? shafts andclose .the slots to-prevent"escape of the shafts. The hooked ends of the latches Amay form half bearings for the shafts to rmit their rotation in the bearing formed y the end of the s lot and the hooked portion of the latch.

The friction gear wheel 4,8 is operated 130 thru a pawl 56, pivoted at one end on a pin 56 on the reciprocatory bar -22 and,

aving a tooth at its op osite end held 1n yielding engagementwiti the driven gear u ring the operation'of the machine, the pewl' will operate the friction gear wheel ,4 step by step to eti'ect operation ot the rewind roller 43. To vprevent retrograde movement Aof the friction gearr wheelby' 4backdrag of the pawl 56, I :provide a stop paw] 57', Awhich is pivoted to the* frame 40 a pin 40 and has a tooth 57, engage a le with the friction gear member 49 to hold it against rearward movement, the

pawl being extended and connected with the s ring 57, so that afsingle spring serves to yiel ly hold both of the pawls to the gear w eel. ,y

VThe secondary rewind roller is driven synchronously with the primary roller, but independently' thereof, through a ear wheel 38' on the roller shaft, a gear w eel 53"on the platen shaft and intermediate gear wheels 53 and 54 on the frame plate 9, theintermediate gear wheel 54 being a friction ar wheel like the wheel 48 Ythrough w ich the primary roller is driven.

second arm 'engageable with the stud 33 on the slide bar 22, so that when the sec ondary shaft is operated clockwise the stud 61 engages the lever arm 62 and moves the arm 64 against the stud-33 to shift the slide bar rearwardly against the tensionof its springr 30. The lever is returned by the slide bar, but the returnmovement is supplemented by a spring 65 connected with the lever arm 62 and with ithe portion of the frame'upon which the lever is mounted.

The paper strip 66 is contained in a roll 67 wound on a roller 68 that is rotatably mounted on a. shaft 9, slidably mounted in slots 70 in the arms o a U bracket 71 mounted on the rear end of the table L 7, so that the roll may have vertical movement in its supporting frame to compensate for withdrawal of the strip. The roll has no fixed support in the frame, but rests on a roller 72 extending transversely between the frame arms and which also serves as a guide for the strip as it leaves the roll to enter the printing mechanism. After passing over the combineddsupporting and guide roller 7 2 the strip passes over a guide roller 73 lo cated adjacent the platen, around the platen and back to the rewind rollers.

s' AWirbel! a duplicate record is desired a;

duplicate strip 1s employed, one of the members of which has 1a carbon back, soA that it willprint onvtheA mating strip. 'The double strip -is combinedinthe r'ollfbut separated after itpasses the platen, so thatthe-duplicatemay'rewind ontheroller 38 and the original on the roller 513. With this arrangement the primary strip may be' removed daily or at any vother period, and the secondary strip at longer intervals, the record of the two strips being identical, however,`

because of the simultaneous printing by the inked ribbon on the original or rimary strip andby the carbon on the dup icate or secondary strip.Y

It is apparent that the a paratus may be used for a single strip record) by allowing one of the rewind rollers to wo'rk idle, and that while I have specifically designated one of the rollers as the primary one and the other asthe secondary one, such arrangement is not essential, but has been specified merely as the most convenient `arrangement. The present improvement may be considered as an addition to the printing mechanism of the main register to which Ihave referred, as the U frame 40 and its rewind' roller may be installed or removed without aii'ecting the single record mechanism. I have not attempted to describe the detail operation of the main register, as this is fully disclosed in the patent to which I have referred and with `which the present mechanism is adapted for use.

What I claim and desire to secure by Letters Patent is:

1. The combination of a roller upon which a double record strip is wound in overlying plies, a platen, means guiding the strip over the platen in overlying plies, a separate rewind member for each ply of the record strip, and means operating the rewind members simultaneously.

2. In combination with a printing mechanism, a pair of independently rotatable rewind rollers, a pinion on each rewind roller` a friction gear wheel 'operably connected with each pinion, a slide bar, a pawl on the slide bar engaging one of the friction gear wheels, intermediate gearing connected with the other friction gear wheel, and a pawl on the. slide bar operating the' intermediate gearing whereby bothV of the rewind rollers are actuated upon reciprocation of the bar.

3. In combination with a main stationary frame, a rewind roller rotatablel on the frame. a supplemental, stationary frame, a rewind roller on the supplemental frame, pinions on the rewind rollers, a gear wheel on the supplemental frame, meshing with the pinions on one of the rewind rollers, a
